i cant seem t figure out what is going on here. The Linux machine I am using is running as a VM on a Win7 machine using Virtual Box running as a service. If i ping the win7 Host i get ok result.

[email protected]:/home/glennwiz# ping -c 100000 -s 10 -i 0.02 192.168.1.100
PING 192.168.1.100 (192.168.1.100) 10(38) bytes of data.
18 bytes from 192.168.1.100: icmp_seq=1 ttl=128 time=1.78 ms
18 bytes from 192.168.1.100: icmp_seq=2 ttl=128 time=1.68 ms

if i ping localhost im ok

[email protected]:/home/glennwiz# ping -c 100000 -s 10 -i 0.02 localhost
PING localhost (127.0.0.1) 10(38) bytes of data.
18 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.255 ms
18 bytes from localhost (127.0.0.1): icmp_seq=2 ttl=64 time=0.221 ms

but if i ping gateway i get DUP packets

[email protected]:/home/glennwiz#  ping -c 100000 -s 10 -i 0.02 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 10(38) bytes of data.
18 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=1.27 ms
18 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=1.46 ms (DUP!)
18 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=22.1 ms
18 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=22.4 ms (DUP!)

if i ping other machine on same LAN i stil get dups.

pinging remote hosts also gives (DUP!) result

[email protected]:/home/glennwiz#  ping -c 100000 -s 10 -i 0.02 www.vg.no
PING www.vg.no (195.88.55.16) 10(38) bytes of data.

18 bytes from www.vg.no (195.88.55.16): icmp_seq=1 ttl=245 time=10.3 ms (DUP!)
18 bytes from www.vg.no (195.88.55.16): icmp_seq=2 ttl=245 time=10.3 ms
18 bytes from www.vg.no (195.88.55.16): icmp_seq=2 ttl=245 time=10.6 ms (DUP!)
